Needs validationmedium risk
An automotive-grade (AEC-Q200) upgrade, but lacks the recommended power safety margin.
Best Alternatives to RC-02K1004FT
Finding a substitute for the RC-02K1004FT 1MΩ 1% 0402 resistor requires checking power ratings and package size. Several options exist with varying trade-offs.
AI replacement insight
Electrical riskmedium
Power rating does not meet 1.5x safety factor for same-size parts.
Package riskhigh
Only applies to functional alternates in different packages like 1206.
Sourcing risklow
Multiple vendors offer similar parts.
Can it be replaced directly?
No direct drop-in replacement that meets the 1.5x power safety factor has been identified. All 0402 package alternatives have the same 0.0625W power rating as the target.
Best replacement path
For a form-fit match, Yageo's AC0402FR-071ML is an automotive-grade option, but you must verify power dissipation. For new designs, FH's RS-06K1004FT offers higher power in a 1206 package.
Main risk
The primary risk is the lack of power derating in same-package alternatives. The target's 0.0625W rating is common, and substitutes do not offer a safety margin.
